BackgroundNo European data currently describe the relation between neighbourhood socio-economic status (SES) and rates of out-of-hospital cardiac arrest (OHCA) bystander cardiopulmonary resuscitation (CPR). This study aims to analyse this effect with a robust deprivation index.MethodsData about all OHCA in Paris were collected prospectively between 2000 and 2010. A geographical neighbourhood unit was assigned to each case. Median household income, and rates of blue-collar workers, unemployment, and adults without high school diplomas were selected as SES characteristics and used to classify neighbourhoods as low SES or higher SES. We analysed the relationship between neighbourhood SES characteristics and the probability of receiving bystander CPR.ResultsOf the 4009 OHCA with mappable addresses recorded, 777 (19.4%) received bystander CPR. Compared to OHCA who did not receive bystander CPR, those receiving CPR were significantly more likely to have occurred in public locations, have had a witness to their OHCA, and not to have collapsed in a low SES neighbourhood, or in a neighbourhood with a median household income in the lowest quartile and with rates of no high school diplomas and blue-collar workers in the highest quartile. In the multilevel analyses, bystander CPR provision was significantly less frequent in low than in higher SES neighbourhoods (OR 0.85; 95% confidence interval [CI] 0.72-0.99).ConclusionIn the city of Paris, OHCA victims were less likely to receive bystander CPR in low SES neighbourhoods. These first European data are consistent with observations in North America and Asia.Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.
